I discarded the patches that I had manually merged last week and
pulled work/thumb2 instead.

The size of MLO dropped from 47604 to 35052 bytes. However, it didn't
boot successfully on the board. The MLO generated after removing
CONFIG_THUMB2_BAREBOX came up fine.

BTW, I while merging this patch, I saw a warning that could be fixed
before merging the patch into master.
  8917ac1 : Applying: ARM: move exception vectors away from start of binary

/home/premi/barebox/.git/rebase-apply/patch:236: new blank line at EOF.
